The QFX SBX-1518BTL is a portable PA Speaker that combines Bluetooth pairing, USB/SD card playing/recording with remote control, and an FM radio tuner into a compact and powerful form factor. For sound reproduction, the speaker uses one 15" woofer with a 60 oz magnet and a horn tweeter with a 23 oz magnet, powered by an internal 300W RMS amplifier to deliver a frequency response of 50 to 20,000 Hz. For I/O, the unit includes a rear panel microphone input with dedicated gain control on both 1/4" TRS and XLR-3F inputs, and a rear panel line level input with a dedicated gain control on both 1/4" TRS and XLR-3F inputs. Rear panel 1/4" and Speakon outputs allow for the signal to be passed on to additional powered monitors for configuring larger systems.

For visual appeal, the speaker features an LED lit grille and for portability it features an integrated handle bar and wheels. An integrated 36mm pole mount socket allows for the cabinet to be stand-mounted, but does not require a large footprint tripod stand. The rear panel 5-band EQ allows you to fine-tune the speaker's response, and the included 3.5mm stereo male to 2x RCA cable will help you get up and running out of the box. For I/O the speaker includes a 1/4" mic input, an RCA input, and a guitar jack. The unit comes with a remote control.
